It runs on a constant torque motor, which delivers quieter, more efficient airflow distribution compared to standard PSC motors. Designed for residential forced-air heating systems, this unit is typically installed by licensed HVAC technicians in new construction or replacement applications where upflow or horizontal duct configurations are required. The gray cabinet is pre-formed with crimped heat exchangers rather than welded, supporting long-term durability and consistent performance across heating seasons.\u003c\/p\u003e\u003cp\u003eThis furnace is suited for residential applications requiring a 4-ton compatible air handler pairing and a single-stage heating configuration. Upflow and horizontal airflow orientation makes it a fit for basement, closet, or attic installations where duct layout allows either discharge direction. The 90,000 BTU\/h capacity and 80% AFUE rating position it for cold-climate regions where adequate heating output is required without the added cost of high-efficiency condensing equipment. Installation follows standard natural or LP gas furnace practices for single-stage systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80% AFUE single-stage heating with 90,000 BTU\/h output\u003c\/li\u003e\n\u003cli\u003eConstant torque motor for quieter operation and more consistent airflow\u003c\/li\u003e\n\u003cli\u003eUpflow and horizontal airflow configuration for flexible installation orientation\u003c\/li\u003e\n\u003cli\u003eCrimped (not welded) heat exchangers using Insta-Position Technology pre-formed flanges\u003c\/li\u003e\n\u003cli\u003eLimited lifetime heat exchanger warranty with registration\u003c\/li\u003e\n\u003cli\u003e4-ton system capacity compatible with matched cooling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style upflow and horizontal flow gas furnace for residential forced-air heating systems requiring a single-stage, 80% AFUE, 90,000 BTU\/h unit with 4-ton airflow capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer written instructions.
